[PATCH V3 0/2] remoteproc: imx_rproc: support i.MX8ULP

From: Peng Fan (OSS) <hidden>

From: Peng Fan <peng.fan@nxp.com>

V3:
 Per Fabio's comment, keep the entries in alphabetical order in Patch 1.

V2:
 Add R-b from Mathieu
 Add Rob in Cc for dt-bindings

i.MX8ULP features a M33 core + dual A35 core, M33 is kicked by ROM,
so like 7ULP, A35 only communicate with M33.

Based linux-next/master 6-22

Peng Fan (2):
  dt-bindings: remoteproc: imx_rproc: support i.MX8ULP
  remoteproc: imx_rproc: support i.MX8ULP

[PATCH V3 2/2] remoteproc: imx_rproc: support i.MX8ULP

From: Peng Fan (OSS) <hidden>
Date: 2021-06-22 05:28:40 

From: Peng Fan <peng.fan@nxp.com>

i.MX8ULP is a new SoC with Ultra low power support, it has a Cortex-M33
core and two Cortex-A35 cores. We need to add new configuration because
it could not reuse the previous i.MX7/8 configuration.

i.MX8ULP M33 core is kicked by ROM, it is not under control of A35 core.
So need to mark the method is IMX_RPROC_NONE.
